OUTLET VALVE.

Application led September To all itc/i017?, t may concern.'

Be it known that we, PrriLir W7. BOLTON and llinnraar N. Mrivninamcitizens of the United States, residing at Colfeyville, in the county of Montgomery and State of Kansas, have invented certain new and useful improvements in Outlet Valves; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

This invention relates to an outlet valve particularly,adapted for use in connection with tank cars.

'lt is aimed to provide a generally improved, simplilied and more efficient valve and particularly one which uses screw threads at less locations than'the valve rdisclosed .in our pending application Serial No. 427 ,316, to the end that the valve may be more readily operated and manufactured and assembled at less cost.

Other objects are to provide a novel means of attachment and of the valve casing and a novel connection between the valve` head or disk and its operating stem.

Various additional objects andv advantages will become apparentfrom a consideration of the descriptionV following taken in connection with accompanying drawings.

1n said drawings Figure 1 is a view in vertical section illustrating the improved valve as connected to a tank car;

Figure 2 is a view partly in side elevation and partly in section illustrating the valve casing;

Figure 3 is a plan view of the valve head or disk and Figure 4 is a side elevation of said valve head or disk.

Like reference characters designate like or similar parts in the different views.

Infcarrying out the invention, the outlet valve is adapted for connection to a tank car for the same purpose as in ourpending application 427 ,316 aforesaid, and the wall of such a tank car is fragmentarily suggested at A.

The valve includes a cylindrical body 10 which is partly disposed in and snugly fits an outlet opening 11 through the wall A at its lowermost portion..

Body or casing 10 has an extension 12 disposed below the wall A', which is prefer-a` ing, a set Vor other fastenings 27a.

1, 1923. Serial No.'660,512.

ably reduced in diameter and provided with screw threads at 13 in order to accommodate a securing nut 14 over-lapping the lower surfaceV of the wall A. .integral with the casing 10 is a laterally extending securing lug 15 which overlaps the upper or inner surfaceof the wall A so that in combination therewith, the nut 14 will clamp'the Vcasing to the wall A. To add to the securityV of engagementof lug 15 with wall A and prevent possible turning of the casscrew 16 is screw threaded through the lug 15 and into wall A.

`,ltension 12 has an inwardly extending flange 17 which supports a removable valve seat 13`whose seatingvsurface 19 is preferably spherical as shown. Surface 1S adapted to be normally engaged by face of similar shape of a valve head or disk 20 whereby thek tank car and valve will be normally closed. rlhe valve seat 13 affords a relatively narrowsurface for engagement by the valve which reduces the possibility of sticking of the valve and enables the valve seat to be more rapidly and readily ground. Y

When the valve head or disk 20 is in open position as shown in Figure 1, the contents of the car may escape throughone or more openings or ports 211 provided in the valve body 'in vcommunicationy with the interior of the tank car,l through said body, and thence through an outlet nozzle 22.V Nozzle 22 is secured to the wall A rby rivets or other fastenings 23 and it has recesses as at 24 in order'` to snugly accommodate the eXtension 12 and nut 14. It will be realized that the nozzle 22 like in our application 427,316

aforesaid, is attached to the car 0r wall A independently of the valve so that if the knozzle should be broken from the car, it

will not disturb the fastening of the valve to the car.

The body or casing 10 adjacent the top has one or more vent openings or ports 25 to enable release of the air within the cas-v ing incidental to opening of the valve. At the top, thevalve casing 1() has an outwardly extending ilange 26 which is engaged by a cap 27 secured thereto by bolts A gasket 28 may be interposed between the top of the body 10 and said cap-27.

Cap 27 has a sleeve or collai` 30 provided with interior screw threads as shown which are in engagement with the ,Screw threads 3l or" a rotatable valve rod 32. Valve rod 32 at its lower' end has an annular flange 33 which is adapted Yfor sliding connection with the valve head or disk 20 as the latter has a key-shaped slot 34 in its upper surface. When the flange 33 is disposed in the recess or slot 34 and the disk is located Within the casing l0, the latter is prevented from detachment from the stem 32. Thus the valve head or disk 2O can only be applied or removed from the stem, when the latter is disengaged 'from the casing and which latter disengagement is only possible when the cap 27 is disengaged from body l0.

The valve stem 32 is adapted for actuation in any suitable manner. For instance it has a handle extension rod 85 detachably engaged therewith as it has a square socket 36 in Which a square stud 37 or'I the stem 32 is disposed. A handle or operating member 38 is provided on rod 35 and the rotation or movement of the rod 35 is under control of a pawvl and ratchet or' lock means generally designated 9 and Which may be similar or substantially similar to the ratchet gear 23 and associated parts, as disclosed particularly in Figures l and 5 0In said pending application 427,316.

' In operation, considering that valve or disk 20 is in engagement .With the seat 18 and thus closed, such valve may be opened through manipulation of the handle 38 in order to uncover' the seat 18 and permit the contents of the car A to discharge through the ports 2l, casing l0 and nozzle 22. The handle 38 is operated in the reverse direction when it is desired to close or seat the Valve 2O in order to stop the discharge of the contents of the car.

Changes in the details may be resorted to provided they tall Within the spirit and scope of the invention.

VJ e claim as our invention:-

A valve of the class described, in combination with a support, the valve having a casing adapted for snug disposition in an opening of the support, a lug` extending inf tegrally from the casing and overlapping the support, a tastening element securing said lug to tl e support, said casing vhaving with the saouldei of tion ot said extension therewith and intimately contacting with and overlapping the opposite face of the support to that engaged by said lug, .said extension having an inwardly extending liange integral therewith, a valve seat disposed on said Jlf'lange, said casing having an outlet opening through said flange, a discharge nozzle in communication with the casing providedv With a recess snugly receiving said extension and said nut, said nozzle about said extension and nut intimately contacting with the under face o1 the support, means to secure the nozzle to the support, a valve head operable in said casing to engage and disensaid seat, said casing having vent openings and an outwardly extending flange at its upper end, a cap secured to the latter flange, said cap having a sleeve pro vided With interior screw threads, and an operating stein for said valve head extending through said sleeve.v 4

In testimony whereof We oursignae tures in presence of tivo Witnesses.
